Australia might have a reputation for sunshine and surfing, but winter is a different story. Especially in Victoria, South Australia, and Tassie — winter brings low temperatures and wild weather conditions, from rain to frost and wind. For many Aussies, it’s important to think about how well your home is prepared for the season ahead.

That’s where SEMCO Works Liquid Membrane comes in. Our flexible, multi-purpose waterproofing solution can help safeguard your home from water and weather damage. Here’s how to put it to work and winter-proof key areas around your home.

Reinforce Your Roof Against Leaks

Your roof bears the brunt of winter’s worst. Even small cracks or gaps can lead to water infiltration and long-term damage, especially when it gets battered with wind. Applying SEMCO Works liquid waterproofing membrane creates a continuous, watertight seal across vulnerable areas.

How to use it:

• Start with a clean, dry roof surface free of debris.
• Apply the membrane with a roller or brush, focusing on joins, seams, and existing cracks.
• Let it cure according to the product guidelines.

From here, you can resurface directly over the membrane with new roofing. Alternatively, choose one of our colours to leave as a finished top coat, or paint over it using a water-based paint for best results.

Shield Your Foundation and Basement

Cold and moisture can creep in through foundation walls, causing structural stress, mould, or water damage. A coat of Liquid Membrane helps stop that in its tracks.

Steps to apply:

• If needed, dig around the base of your home to expose exterior walls.
• Clean the surface thoroughly.
• Apply the membrane evenly over the walls using a brush, roller, or spray system.
• Once dry, backfill the area to further protect the barrier.

Stop Drafts Around Doors and Windows

Why not seal up those sneaky winter draughts around windows and doors. Use SEMCO Liquid Membrane to bridge small gaps and cracks for better insulation (up to 6mm). This can also help to prevent condensation from forming inside by stopping cold air and water ingress, improving insulation and reducing the overall moisture load inside the home.

Here’s how:

• Inspect the perimeters for air leaks or deteriorated caulking.
• Clean the area for optimal adhesion.
• Apply the membrane into gaps and seams to create a seamless, flexible seal.
• Let it dry fully before applying any paint or finish.

Waterproof High-Traffic Outdoor Areas

Patios, decks, and steps are all exposed to rain, frost, and foot traffic, which can lead to deterioration. A coat of Liquid Membrane creates a non-slip, weather-resistant barrier that lasts.

Application tips:

• Start with a clean surface — remove grime, moss, and any loose material.
• Patch any visible cracks or damage.
• Roll or brush on the membrane evenly, and apply extra coats as needed for high-use areas.

Getting your home winter-ready doesn't have to be overwhelming. With our multi-use liquid waterproofing membrane, you can take proactive steps to protect key areas — extending the life of your property. Whether you're sealing your roof or weatherproofing your windows, this versatile membrane makes winter prep easier and more effective.
